Abstract

A method to determine the locating point in convex hull of four control points pertaining to a rational cubic Bezier curve is presented.Comparing to the shoulder point in (Forrest,1980),the locating point exists in a larger field and offers more flexibility in controlling the shape of curves on computer.
